9-year-old millionaire with fashion line is the next Olsen twin

The Olsen twins have told us from a young age that "It Takes Two," but that may not be the case.

9-year-old Isabella Barrett is becoming a fashion mogul in her own right. Barrett's first claim to fame was during her stint on TLC's "Toddlers and Tiaras." The reality series showcased her pageant skills, among others. By the age of six, Barrett was already a millionaire.

Now she's building a fashion empire. Barrett has two companies, named Glitzy Girl and Bound by the Crown Couture. She even had the opportunity to walk the runway during New York Fashion Week, modeling her latest line.

Sales have been soaring, and her mother estimates the pageant princess's net worth to be upward of several million dollars.

She has even dabbled in music. With two songs already produced, Barrett is in the studio working on two more.
